EMDN C02: Arrhythmology Devices
Complete hierarchy for EMDN group C02 in category C (Cardiocirculatory System Devices): 31 terminal codes, EMDN v2026. Terminal codes are the ones accepted in a EUDAMED device record.
Registered classes, as of 8 Sep 2026. For each code with at least 20 registrations under a legislation, the chip shows how devices registered in EUDAMED under that code are classed, counted once per primary UDI-DI and kept separate for each legislation. It is not a determination. The class of a device comes from the MDR and IVDR classification rules for its intended purpose. MDD and IVDD classes are the directive classification and can differ from the class the same device would have under MDR or IVDR.

C0299Arrhythmology Devices - Otherterminal
How C02 is structured
The Arrhythmology Devices branch runs 3 levels deep. 7 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 31 codes marked terminal.
8 terminal codes are “- Other” entries and 5 are “- Accessories” entries, 42% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.
The largest sub-branch is C0201 (Cardiac Electrophysiology and Mapping Devices), holding 10 of the 31 terminal codes.
Frequently asked questions
- Which C02 codes can be used in a EUDAMED device record?
- 31 of the 38 codes listed under C02 (Arrhythmology Devices) are terminal and can be selected. The other 7 are branch headings that cannot.
- How deep is the C02 hierarchy?
- The C02 branch runs 3 levels below the group code. Its largest sub-branch is C0201 (Cardiac Electrophysiology and Mapping Devices), which holds 10 of the 31 terminal codes.
- How many C02 codes are catch-all entries?
- 8 terminal codes under C02 are "- Other" entries and 5 are "- Accessories" entries, 42% of the branch. The remaining 18 name a specific device type.
Not sure which level to stop at, or which of two plausible codes to submit? The guide to choosing an EMDN code walks the decision level by level, with a worked example and the mistakes that get a EUDAMED registration rejected.
